If you see that it is parallel. You can see that each angle on the top and bottom of it equals 360 degrees. So if the same 360 degree angle is at the bottom of these both. And both of then have 2 180 equalling degrees on the top and bottom of it. Then that would mean for the 125 the other side would have 55 degrees equalling 180. Same for the bottom so that would mean that it would be the same for the bottom 360 degree angle making me absolutely sure that X is equal to 55 degrees.
